Totally agree. I liked posterous. I've also wondered out loud whether a similar thing will happen to workflowy as well, which I also love.

Nothing against the guys, they're just optimizing, but it sucks to be on the receiving end. Is web 4.0 going to be a DIY world where vps-es are the only "services" you'll need and other products will have to plug in to what you host on your own vps just like normal purchased desktop software?
